These are the posters in my room :
Modern lifestyle chart (imo my crappiest poster)

Mind warp

The courtyard by Irvine Peacock

Trainspotting

and Scarface (the one "say hello to my little friend", couldn't find the exact one)
I also have Dali's "Temptation of St. Anthony" in my room at my parents house.

Only a poster ofcourse, not the real one

Anyway, I hoped this helped a bit. You should just find one of those gift stores, usually there's loads of posters there.
